At a real campfire, if you're foul-mouthed, hateful, and a generally bad human spewing nonsense in front of my wife and children, I can face you man to man and teach you some manners. Half the people here wouldn't treat people as they do here face to face at a real campfire. Anonymity of the internet and all.
You can be asked to leave or be escorted away from a real campfire, too...or simply removed by whatever means deemed appropriate. If you don't like the company here you are free to vacate the area.
